In this class we will begin by talking about how we hear. It helps to know a little about the ear in order to appreciate our sense of hearing and to protect ourselves while working. We then move on to tuning stability, so essential for our work. We need to be able to get the instrument to stay in tune and be limited in that regard by the instrument, not by our tuning techniques. We will explore the movements of the tuning pin and how to utilize them to help in stabilizing our tunings.
